The Study on the Characteristics of Leakage Circuit Breakers in Protection of the Low Voltage Electrical Apparatus

저압전기기기의 보호를 위한 전류동작형 누전차단기의 특성에 관한 연구

This study on the characteristics of the leakage circuit breakers handles the rolls of each itemized parts of the mentioned apparatus and their influence in determining of the characteristic curve of leakage circuit breaker. Furthermore the differential current transforms in the mentioned apparatus for detecting the fault is handled as a heavy point.
